Maybe. I won't argue it. But, from what I see around me, more affective is how younger family members, neighbors, sales people, care takers, all those who are in a position to take charge think they have to do so. The pressure from them can be overwhelming. I know elderly people who talk about it. They know their children are trying to be helpful but they aren't leaving their parents any freedom.
Two sides to every story, maybe?
